And Scotland Under-21 star Christie has moved to Pittodrie in a bid to get first-team football.

Dons boss Derek McInnes told afc.co.uk: “I am delighted to get a player of Ryan’s quality into the club.

“We want to make a couple of additions in the January window – quality additions – and there is no doubt Ryan has the quality to come in and make an impact with us. Ryan can help us with the challenges that lie ahead during the second half of the season.

“I would also like to thank Brendan Rodgers and Celtic for assisting in getting the deal done.”

Celts boss Brendan Rodgers still sees him as part of his long-term plans but hopes more experience will help his development.

Christie, 21, joined the Hoops from Inverness Caledonian Thistle in the summer of 2015 – but was loaned back for six months.

He teamed up with Celtic in January 2016 and featured occasionally under Ronny Deila.
